Always switch off the ignition and take the key with you when
leaving the vehicle - even if you on ly intend to be gone for a short
time. This is especially im portant if children are left in the car. They
might otherwise be able to start the engine or use power-operated
equipment such as the electric windows - this could lead to inju-
ries.
•
Wait for the vehicle to come to a standstill before removing the
ignition key from the lock. Otherwise the steering lock could
engage suddenly, causing an accident.Note
The function of the remote control key may be impaired by interfer-
ence from other nearby radio signals (for example from a mobile
telephone or TV transmitter) if these are in the same frequency
range.Indicator lamp on remote control key
The indicator lamp on the remote control key lights up
when you press the buttons.
The indicator lamp should light up once briefly when you press one
of the buttons briefly. The indicator lamp should flash when you
press and hold one of the buttons (convenience open/close).
If the indicator lamp does not li ght up, this means the battery is
exhausted and must be replaced ⇒page 40 . The instrument cluster

Technical data
Lock function can be switched on and off on the sound system or
MMI*
⇒page 44 .
In the event of an accident in which the airbags inflate, the doors
will be automatically unlocked to facilitate access and assistance.
Deadlock mechanism
The central locking system is combined with a deadlock mecha-
nism. Once the vehicle has been locked from the outside, the door
handles on the inside are deactivated. This makes it more difficult
to break into the vehicle.
Anti-theft alarm system*
If the anti-theft alarm system senses interference with the vehicle it
triggers an audible and visible alarm.
The anti-theft alarm system switches on automatically when the
vehicle is locked. It switches off automatically if you unlock the
vehicle using the remote control.
If you unlock the vehicle by inserting the key in the drivers door, the
ignition must be switched on within 15 seconds, otherwise the
alarm will be triggered. On some export versions, the alarm is trig-
gered immediately when you open a door.
To deactivate the alar m, press the unlock button on the remote
control key or switch on the ignition . The alarm will also switch itself
off when it comes to the end of its cycle.
Switch off the interior monitor an d tow-away protection if you wish
to prevent the alarm from be ing triggered accidentally.
Turn signals
The turn signals will flash twice when the vehicle is unlocked and
once when the vehicle is locked. If the turn signals do not flash, one
of the doors, the bonnet or the boot lid is still open.
Accidental lock-out
The central locking system prevents you from being locked out of
the vehicle in the following situations:
•
When the driver's door is open, it cannot be locked together with
the other door by pressing the central locking switch and then
closing the door ⇒page 47 .
•
On vehicles with advanced key*, the boot lid will be released
again automatically if the remote control key that was last in use is
left inside the boot when the boot lid is closed ⇒page 48 .
To prevent yourself from being locked out, do not lock the vehicle
with the remote control key before closing the doors or boot lid.
WARNING
Do not leave anyone (especially child ren) in the car if it is locked
from the outside and the deadlock mechanism is activated: the
doors and windows cannot then be opened from the inside.
Locked doors could delay assistance in an emergency, potentially
putting lives at risk.
Note
•
Never leave any valuable items in the vehicle unattended. Even a
locked vehicle is not a safe.
•
If the diode on the driver's window sill lights up for about 30
seconds when the vehicle is locked, the central locking system or
anti-theft alarm* is not working properly. Please have the malfunc-
tion repaired by an Audi dealer or qualified workshop.
•
The interior monitor of the anti-t heft alarm* system will only
function as intended if the windows and the tilting panorama roof*
are closed.
